Very strange issue I've run into. I can live with it, but I want to remove this issue as soon as I possibly can. I just have no idea what to do or where to start.

When I'm indoors, there's no issue. But when I step outdoors, there is a white line that runs horizontal and parallel to the sea level and fades away about half an inch down the screen. It goes away if I pause the game in any way.

I've never had this issue before, and it only happened when I booted up the game with MGSO. However, MGSO is the reason I want to re-visit the game. I'm thinking it has something to do with the distant land generator, but I truly have no idea what's causing it or where to start in order to remove it.

If anyone needs a picture, I'll try and get one up. Thanks in advance.

I'm pretty sure this is a problem with your MGE settings.
Moving to the mod forum, so that some of the MGE experts will see your problem.
